What does exempt mean?
You can "NOT route" packets via a wg interface (fix your routing,
subnets, etc.), or BLOCK packets with a firewall (e.g. nftables,
iptables). 1st is better if possible (requires redesign), 2nd may be
easier. Combining both is the best.

"samba shares" is like "red car"...
there are quite a few protocols involved with them, most of them run
atop UDP and TCP or both.

... cannot help you much here, but I guess it is some tcp, udp and rtp
mix to some large cloud of IPs.

draw a map (on paper) or ascii art or something, put some IP
addresses, fake if you are worried.

Those are some (aadvanced) routing rules, you probably can live with
standard, if you can choose the IP addresses/networks you connect to
(home).

Really, try to draw a diagram. If you cannot - then it is probably too
complex and wireguard is not gonna help you.
